1.建立一个maven工程
2.在pom.xml导入mybatis自动生成代码插件
<!-- mybatis generator 自动生成代码插件 --> <plugin> <groupId>org.mybatis.generator</groupId> <artifactId>mybatis-generator-maven-plugin</artifactId> <version>1.3.6</version> <configuration> <configurationFile>${basedir}/src/main/resources/generator/config.xml</configurationFile> <overwrite>true</overwrite> <verbose>true</verbose> </configuration> </plugin>
3.建立mybatis-config.xml配置自动生成插件
<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE generatorConfiguration PUBLIC "-//mybatis.org//DTD MyBatis Generator Configuration 1.0//EN" "http://mybatis.org/dtd/mybatis-generator-config_1_0.dtd"> <generatorConfiguration> <!-- 数据库驱动:选择你的本地硬盘上面的数据库驱动包mysql-connector-java-5.1.39 --> <classPathEntry location="D:\repo\mysql\mysql-connector-java\5.1.6\mysql-connector-Java-5.1.6.jar" /> <context id="DB2Tables" targetRuntime="MyBatis3"> <commentGenerator> <property name="suppressDate" value="true" /> <!-- 是否去除自动生成的注释 true:是 : false:否 --> <property name="suppressAllComments" value="true" /> </commentGenerator> <!--数据库链接URL,用户名、密码 --> <jdbcConnection driverClass="com.mysql.jdbc.Driver" connectionURL="jdbc:mysql://ip:3306/db?useSSL=false&useUnicode=true&characterEncoding=utf-8&serverTimezone=GMT%2B8" userId="user" password="pwd"/> <!-- 类型转换 --> <javaTypeResolver> <!-- 是否使用bigDecimal, false可自动转化以下类型(Long, Integer, Short, etc.) --> <property name="forceBigDecimals" value="false" /> </javaTypeResolver> <!-- 生成模型的包名和位置 --> <javaModelGenerator targetPackage="com.eastcom.bas.entity" targetProject="src/main/java"> <property name="enableSubPackages" value="true" /> <property name="trimStrings" value="true" /> </javaModelGenerator> <!-- 生成映射文件的包名和位置 --> <sqlMapGenerator targetPackage="mapper" targetProject="src/main/resources"> <property name="enableSubPackages" value="true" /> </sqlMapGenerator> <!-- 生成DAO的包名和位置 --> <javaClientGenerator type="XMLMAPPER" targetPackage="com.eastcom.bas.mapper" targetProject="src/main/java"> <property name="enableSubPackages" value="true" /> </javaClientGenerator> <!-- 要生成的表 tableName是数据库中的表名或视图名 domainObjectName是实体类名 --> <table tableName="tb_user" domainObjectName="User" enableCountByExample="false" enableUpdateByExample="false" enableDeleteByExample="false" enableSelectByExample="false" selectByExampleQueryId="false"> <property name="useActualColumnNames" value="false"/> </table> </context> </generatorConfiguration>
4.运行执行mybatis-config.xml
执行步骤:maven bulid -> mybatis-generator:generate -e
